Question

您好我是rails的初学者，当我尝试运行rspec capybara测试时会遇到一些问题。

require 'rails_helper'

describe "Upload Process", :type => :feature do

  it "Can upload a file" do
    visit new_document_path
    page.attach_file('file', '/Users/yaomin/Desktop/my_travel_pic/uploadtest.jpg', visible: false)
    click_button 'Upload'
    page.should have_content("Uploadtest")
  end
end

但是我收到了错误

Failures:

  1) Upload Process Can upload a file
     Failure/Error: attach_file('file', '/Users/yaomin/Desktop/my_travel_pic/uploadtest.jpg', visible: false)

     Capybara::ElementNotFound:

Finished in 0.40034 seconds (files took 1.99 seconds to load) 1 example, 1 failure

Failed examples:

rspec ./spec/features/upload_test.rb:5 # Upload Process Can upload a file

我的观看代码是

h1 Listing documents

table
  thead
    tr
      th
      th
      th

  tbody
    - @documents.each do |document|
      tr
        td = link_to 'Show', document
        td = link_to 'Edit', edit_document_path(document)
        td = link_to 'Destroy', document, data: { confirm: 'Are you sure?' }, method: :delete

br

= link_to 'New Document', new_document_path

下面是新的文档视图

h1 New document

= render 'form'

= link_to 'Back', documents_path

- if @document.folder
  = link_to "Back to '#{@document.folder.name}' Folder", browse_path(@document.folder)
- else
  = link_to "Back", root_url

和我的表格部分

= form_for @document do |f|
  - if @document.errors.any?
    #error_explanation
      h2 = "#{pluralize(@document.errors.count, "error")} prohibited this document from being saved:"
      ul
        - @document.errors.full_messages.each do |message|
          li = message
  = f.label :file
  = f.file_field :file
  - f.hidden_field :folder_id

  = f.submit "Upload"

有关信息，我实际上可以手动上传文件，但我运行的上传测试失败。

提前感谢您的所有帮助：）

传递给attach_file的第一个参数需要是id，name或关联标签文本。在你的情况下，可能不是'文件'。您声明关联的标签文本是“选择文件”，所以可能类似

attach_file('Choose File', file_path)

是你想要的（如果没有实际的HTML，不可能确切地说出第一个参数应该是什么）。其他可能有效的事情是

attach_file('document_file', file_path) # match the elements id
attach_file('document[file]', file_path) # match the elements name

但同样，第一个参数可能略有不同，HTML将显示它们应该是什么。

文件输入常见的另一个问题是它们可能会被CSS隐藏（透明等），以便在浏览器中设置相同的样式。如果是这种情况并且您使用的是JS驱动程序，则可以使用类似

的内容

attach_file('Choose File', file_path, make_visible: true)

将尝试使该字段可见，设置文件，然后恢复原始CSS。
